Rational-WENO: A lightweight, physically-consistent three-point weighted essentially non-oscillatory scheme

S Shahane, S Chammas, DA Bezgin… - arXiv preprint arXiv …, 2024 - arxiv.org
Conventional WENO3 methods are known to be highly dissipative at lower resolutions,
introducing significant errors in the pre-asymptotic regime. In this paper, we employ a …

OpenACC offloading of the MFC compressible multiphase flow solver on AMD and NVIDIA GPUs

B Wilfong, A Radhakrishnan, HAL Berre… - arXiv preprint arXiv …, 2024 - arxiv.org
GPUs are the heart of the latest generations of supercomputers. We efficiently accelerate a
compressible multiphase flow solver via OpenACC on NVIDIA and AMD Instinct GPUs …

Numerical Investigation of Leakage of High-Amplitude Sound in Ill-Fitting Earplugs

H Yu, KK Ahuja, LN Sankar… - AIAA AVIATION FORUM …, 2024 - arc.aiaa.org
We present a numerical investigation of high-pressure sound waves through small orifice
openings, focusing on earplug leakage. Our long-term goal is to improve earplug design in …

Instability of two-species interfaces via vibration

BA Wilfong, R McMullen, T Koehler… - AIAA AVIATION FORUM …, 2024 - arc.aiaa.org
Vibrating liquid–gas interfaces can break up due to hydrodynamic instability, resulting in gas
injection into the liquid below it. The bubble injection phenomena can alter fluid-structural …
